Unless you have some experience in electronic repair, not much you can usually do. Could be the power supply, could be the logic board, both of fail on TV's a lot, and both of which are expensive to have someone repair, usually to the point that a new TV is cheaper.

I had the same problem with my 55 inch Samsung TV. After checking components on the power supply board I found that the five 33 ohm (orange-orange-black) resistors and changed value. Each resistor measured approximately 3.6 ohms.
I replaced all five resistors. Now the TV works.
